Research Interests

I am interested in how intracellular bacterial pathogens evade the immune system and in identifying pathogenic mechanisms that can be exploited for vaccine development. I recently shifted research focus from zoonotic disease to antibiotic­ resistant nosocomial pathogens. Increasing antimicrobial resistance in hospital­ acquired infections necessitates immediate work towards better vaccination strategies. I love to involve students in my research and believe that it helps to broaden the perspective of medical students in understanding the work involved in bringing medicine from the laboratory to human use.
